AI Technical Summary

Technical Problem

In the prior art, aluminum coils may curl at the edges before roller coating, causing the guide rollers to lose their positioning, the aluminum coils to deviate, and the paint to adhere unevenly during roller coating, which may also damage the equipment.

Method used

An aluminum coil roller coating device was designed, comprising a conveying mechanism, a roller coating mechanism, and an edge straightening mechanism. The edge straightening mechanism flattens the edge of the aluminum coil through a sliding frame, an edge pressing seat, and a roller pressing mechanism. The sliding frame is adjusted by a return spring and a push rod to ensure that the edge of the aluminum coil is flat and to prevent deviation.

Benefits of technology

It effectively prevents uneven coating adhesion at the edges of aluminum coils, reduces aluminum coil offset, protects the roller coating equipment, and ensures the uniformity and integrity of the coating on the aluminum coil surface.

Abstract

The utility model relates to the field of aluminium roll coating, especially a kind of aluminium roll roll coating device, including conveying mechanism, conveying mechanism side is equipped with roll coating mechanism, still including edge trimming mechanism, edge trimming mechanism is located conveying mechanism other side. Two roll mechanisms are rolled on the aluminium roll of movement, to the fold of the edge position of aluminium roll is flattened, simultaneously, two push rods are pushed to the rotation of two dial, and sliding frame moves, then two reset springs pull sliding frame to move back, in this process, the fold of the edge position of aluminium roll front and rear two sides is completely flattened by the driving of two pairs of edge seat by sliding frame, to reduce the uneven condition of paint adhesion caused by roll coating.
